Understanding Dynamics 365 Plugins

Plugins in Dynamics 365 are pieces of code that integrate with the CRM to augment or modify its default behaviour. Essentially, they enhance the efficiency of Dynamics 365 by allowing additional operations to be performed when certain events occur within the system.

Getting Started: Setting up your Development Environment

Before starting, ensure your development environment is primed for writing a plugin. You would need Visual Studio installed on your local machine. Also required is The Microsoft .NET Framework and Dynamics 365 Software Development Kit (SDK) templates.

Writing your First Dynamics 365 Plugin

Step 1: Creating a New Project
Launch Visual Studio, then select ‘New > Project.’, Choose ‘Class Library’ from the list of templates and provide a suitable name for your project.

Step 2: Adding References
Use NuGet package manager to add references to necessary libraries. These include:
– Microsoft.Crm.Sdk.CoreAssemblies
– Microsoft.Crm.Sdk.Deployment
– Microsoft.Crm.Sdk.Workflow

Step 3: Writing the Plugin Code
Create a new class that inherits from the ‘IPlugin’ interface provided in the SDK. Your class should implement the ‘Execute’ method which is the entry point for the plugin. Here, you can control what happens when the plugin is triggered.

Example code:

public class MyPlugin: IPlugin
public void Execute(IServiceProvider serviceProvider)
// Plugin code goes here

Step 4: Registering the Plugin
To use your plugin in Dynamics 365, you have to register it. This process involves adding the assembly (DLL) to the CRM system using Plugin Registration Tool.
